Answer:
284.837734 ft^3 rounded up to 284.84 ft^3
Step-by-step explanation:
Cylinder Volume: pi*r^2h
pi*4^2*4=201.06193
Cone Volume: pi*r^2*(h/3)
pi*4^2*(5/3)=83.7758041
201.06193+83.7758041=284.837734
284.837734 ft^3

Actually Welcome to the concept of Scalar factor Multiplication in Matrix.
So from the above matrix, -3A , is just simply multiplying the -3 to every element of the matrix, so we get as,
===> -3A = | -9 -18 |
| -24 -21 |
| -6 6 |
hence the correct option is B.
The first one is 36 and the second one is -4/7 I believe
Answer:
AD = 230
Step-by-step explanation:
AD = 30x - 10
MN = 31x + 1
BC = 30x + 28
To find the length of AD, we need to generate an equation that will enable us to find the value of x.
Thus,
MN = ½(AD + BC) => Trapezoid Midsegment Theorem
Plug in the values
31x + 1 = ½(30x - 10 + 30x + 28)
(31x + 1) × 2 = 30x - 10 + 30x + 28
62x + 2 = 30x - 10 + 30x + 28
Add like terms
62x + 2 = 60x + 18
62x - 60x = -2 + 18
2x = 16
x = 16/2
x = 8
✅AD = 30x - 10
Plug in the value of x
AD = 30(8) - 10 = 230
